我有一个已经有一个类的元素： <div class="someclass"> <img ... id="image1" name="image1" /> </div> 现在我想创建一个Javascript函数，它将向div添加一个类（不是替换，而是添加）。 我怎样才能做到这一点？ 向元素的className属性添加一个空格和新类的名称。 首先，在元素上添加一个id ，以便您可以轻松获取参考。 <div id="div1" class="someclass"> <img ... id="image1" name
For sending complex JSON/JavaScript objects to C++ binaries over a wire, I am using Protocol Buffers. There is native protobuf support for Node.js these days, so I'm not using any other bindings. // Set maximum execution time of binary to equal the // remainder of processing time, minus a second to allow // for parsing. var timeLimit = context.getRemainingTimeInMillis() - 1000; // Check if
为了通过电线将复杂的JSON / JavaScript对象发送到C ++二进制文件，我使用了协议缓冲区。 这些天有对Node.js的原生protobuf支持，所以我没有使用任何其他绑定。 // Set maximum execution time of binary to equal the // remainder of processing time, minus a second to allow // for parsing. var timeLimit = context.getRemainingTimeInMillis() - 1000; // Check if meta parameters are given in the request. // Assi
I'm using Backbone.js. I am listen to the "add" event of my collection this.listenTo(this.collection, "add", this.addOne); and it will append the view object like this: addOne: function (as) { var v = new XUView({model: as}).render(); $(v.el).prependTo($('#object-list')).hide().fadeIn().slideDown(); } Now I want to automatically remove objects from the view if t
我正在使用Backbone.js。 我正在听我的收藏“添加”事件 this.listenTo(this.collection, "add", this.addOne); 它会像这样附加视图对象： addOne: function (as) { var v = new XUView({model: as}).render(); $(v.el).prependTo($('#object-list')).hide().fadeIn().slideDown(); } 现在，如果项目已从集合中删除，我想从视图中自动删除对象。 我正在收听“删除”事件： this.listenTo(this.collection, "re
I'm using backbone.js to implement a buddy list aka Roster. My backbone view for the Roster collection and individual rosterEntry are as follows: Slx.Roster.Views.RosterEntry = Backbone.View.extend({ tagName: "li", className : "rosterEntry clearfix", templateSelector: '#rosterEntryTemplate', initialize: function() { _.bindAll(this, 'render'); this.model.
我正在使用backbone.js来实现好友列表aka Roster。 我对名册收集和独立的骨干视图rosterEntry如下： Slx.Roster.Views.RosterEntry = Backbone.View.extend({ tagName: "li", className : "rosterEntry clearfix", templateSelector: '#rosterEntryTemplate', initialize: function() { _.bindAll(this, 'render'); this.model.bind('change', this.render); this.model.bind('re
I have a backbone collection and when I remove a model from the collection, I want it to remove the item from a list in the view. My collection is pretty basic MyApp.Collections.CurrentEvents = Backbone.Collection.extend({ model: MyApp.Models.Event }); and in my views I have MyApp.Views.CurrentEventItem = Backbone.View.extend({ el: 'div.current_event', initialize: function(){
我有一个骨干集合，当我从集合中删除模型时，我希望它从视图中的列表中删除该项目。 我的收藏是非常基本的 MyApp.Collections.CurrentEvents = Backbone.Collection.extend({ model: MyApp.Models.Event }); 并以我的观点看待 MyApp.Views.CurrentEventItem = Backbone.View.extend({ el: 'div.current_event', initialize: function(){ event = this.model; _.bindAll(this, "remove");

I have used JSOn stringify many time but never come across this result I have an array of JSON objects [ { "param_2": "Description 1", "param_0": "Name 1", "param_1": "VERSION 1" }, { "param_2": "Description 2", "p
我曾尝试寻找他们的文档的Mozilla JSON stringify页面以及SO和Google的这里，但没有找到任何解释。 我已经使用JSOn很多次，但从来没有遇到过这个结果 我有一个JSON对象数组 [ { "param_2": "Description 1", "param_0": "Name 1", "param_1": "VERSION 1" }, { "param_2": "Description 2", "param_0": "Name 2", "param_1": "VERSION 2" }, {
I have a big object I want to convert to JSON and send. However it has circular structure. I want to toss whatever circular references exist and send whatever can be stringified. How do I do that? Thanks. var obj = { a: "foo", b: obj } I want to stringify obj into: {"a":"foo"} Use JSON.stringify with a custom replacer. For example: // Demo: Circular reference var o = {}; o.o = o;
我有一个大对象我想转换为JSON并发送。 但它有圆形结构。 我想抛弃存在的任何循环引用，并发送任何可以字符串化的东西。 我怎么做？ 谢谢。 var obj = { a: "foo", b: obj } 我想把obj变成： {"a":"foo"} 将JSON.stringify与自定义JSON.stringify一起使用。 例如： // Demo: Circular reference var o = {}; o.o = o; // Note: cache should not be re-used by repeated calls to JSON.stringify. var cache = []
I'm stringyfing an object like {'foo': 'bar'} How can I turn the string back to an object? 你需要JSON.parse()这个字符串。 var str = '{"hello":"world"}'; try { var obj = JSON.parse(str); // this is how you parse a string into JSON document.body.innerHTML += obj.hello; } catch (ex) { console.error(ex); } JSON.parse与JSON.stringify相反。 JSON.stringify and JSON.p
我正在绑定一个对象，如{'foo': 'bar'} 我怎样才能把字符串变回对象？ 你需要JSON.parse()这个字符串。 var str = '{"hello":"world"}'; try { var obj = JSON.parse(str); // this is how you parse a string into JSON document.body.innerHTML += obj.hello; } catch (ex) { console.error(ex); } JSON.parse与JSON.stringify相反。 JSON.stringify和JSON.parse几乎是JSON.stringify ，并且
